SRAM Pg-1230 Nx Eagle 12-Speed Cassette

If you're wanting to cross over to SRAM, but don't wanna (or can't) buy a new wheelset/Hub Body these work great with Eagle (mechanical OR electronic) Derailleurs.

Good deal and quality. Fast shipping

Note that the smallest speed and lock ring is strapped to the back of the rest of the cassette. Don't be like me and complain that it was missing when it is right there.

Ya decir sram es suficiente asi que es muy buena

Que es calidad

This is the second SRAM rear cassette I've installed on my ebike. My first NX Eagle chain/cassette combo I left the chain on for way too long (2,500 miles) and over-stretched it and accidentally wore out my rear cassette too. Costly mistake! I first just attempted to replace my chain to fix some minor skipping but without replacing the rear cassette too the problem just got 100x worse. I rode around for 2 days not allowing my bike to shift into the my slipping gears and ordered this replacement right away. Once this was replaced, along with the chain, my ebike rode like new again. Moral of the story, this is a great product and works well on an ebike. However, I'd highly recommend getting a Park Tool CC-2 to keep a close eye on chain stretch, replace the chain @ .5 to avoid also wearing out your rear cassette and other drive train components. Due to high stresses applied from an ebike motor onto a drive train, via the chain, a new chain is recommended roughly every 1000 miles.

Todo perfecto

I had no issues with a direct replacement of the factory cassette of my 2019 Scott Genius. The fact that I needed to replace it in the first place is the reason for the 4 stars. The compromise between weight-saving and strength went a little too far into weight-saving in my opinion. When I caught a branch while pedaling along on a single track trail, it bent 2 cogs and literally tore the metal apart on one, so it was not repairable. I decided to replace the cassette with the Eagle GX, which is stronger, quite a bit more expensive, and also not compatible (XD driver!), which nobody told me. I learned a bit about hubs in the process, so no harm done. Trying to find an XD driver for my wheels turned out to be impossible, so I upgraded the whole wheel set and went fully carbon, converted the stock wheels to studs and bought this replacement.

Ottima qualità

As described. Used for second set of wheels with Gx system.

Parfait

Moja kolejna kaseta do e-mtb. Solidna, w bardzo dobrej cenie. Prze dobrym traktowaniu i regularnej wymianie lancucha posłuży 2-3 sezony spokojne.

Denna kassett gör det den ska. Med kedja av GX kvalitet eller högre så sker växlingar bra.
